I am trying to create an experiment where two words are presented on the screen. After 1000ms, one of the words (the target word) changes color (or becomes highlighted, or surrounded by a box, or something like that). The target word should sometimes be on the left and sometimes on the right.
The way I went about doing this was to have SuperLab draw from two lists, “targetlist” and “fillerlist”, and have two text events immediately sequential to each other. These events use the two-level trial variable “ScreenPosition” to place each word on the left or the right. Then, after 1000ms, the process is repeated, but this time, the text event that outputs the word from “targetlist” is set to write in red. However, because ScreenPosition is random, sometimes the position of the two words flips. In order for this approach to work, I need SuperLab to be able to “remember” what the previous value of ScreenPosition was, which I don’t think is possible.
So, is there another way to go about solving this problem? Thanks in advance for any ideas or suggestions.
